[A]How was Eccentricity of Outer Core formed?
Degradation of Van Allen Belt at Rio Position[ (External Force) ⇒Isostasy
⇒ (Reason for Movement of Van Allen Belt due to Eccentricity of Earth Axis Current of about 500 km)]
A Theory consistent with Current state of Results = "Multi-Impact Hypothesis".

[B]Origin of Plate Tectonics (= Formation Mechanism) and Driving Force.
Circum-Pacific Archipelago and Back-Arc Basin Formation Mechanism [Collision of CERRA Fragment with Earth and Moon Ejection (Earth Mantle Deficiency = Mantle rise due to Isostasy =Deep Ocean Floor= Average Dpth of about 5 km)]
In Multi-Impact Hypothesis, for the first time in World, Plate Driving Force is assumed to be [Combined Force of Earth's Rotation and Eccentric External Force Moment around Common Center of Gravity of Earth and Moon].

[C]Verification of Multi-Impact Hypothesis of Plate Tectonics.
When we explore Mystery of Origin and discover Formation Mechanism, we want to prove it. There is a Method of Creative Hypothesis and Verification.
In other words, the more Epoch-Making Hypotheses can be established and Results (Characteristics) of Natural Evolution can be rationally explained in a Unified Manner, the more plausible Hypotheses will be. In other words, Origin of Moon and Origin of Jupiter's Great Red Spot could be verified in a Unified Manner. In this way, we were able to verify Origin of Life in Solar System together.

[D]Vertical Movement is Isostasy, Horizontal Movement is Plate Driving Force [Orbital (External Force) Moment between Earth Rotation and Moon (New Theory)] to minimize Inertia Rate.
Vertical Movement is Isostatic, and Vertical Equilibrium Action due to Gravitational Potential becomes a Sphere in Homogeneous Bodies. All Stars and Planets in Universe are Spheres. Blue Sea and Green Land of Earth are miraculous Stars. A. Wegener (Germany) was puzzled by Driving Force of Horizontal Movement of Plete Tectonics, and A. Holmes (UK) proposed Thermal Convection Hypothesis. It was all Internal Forces that did not consider Rotation of Earth. In MIH, Driving Force for Horizontal Movement is assumed to be Minimization of Inertia Rate due to [Orbital (External Force) Moment between Earth and Moon (New Theory)]. As a Verification, Movement Direction of Pacific Plate Suddenly Changes, and Movement and Stop of Antarctic Plate to Rotation Axis are mentioned.

[E]Formation Mechanism of Pacific Rim Archipelago and Backarc Basin, Mechanism of Start of Plate Overlapping, Mechanism of Rapid Change of Pacific Plate Movement Direction
Figure is a Cross-Sectional View including Earth's Axis and Rio de Janeiro City, and is a Schematic Diagram of Mantle Flow Result after Impact by Isostasy. Mantle Defect due to Collision is interpolated by Flow of Surrounding Mantle and causes Eccentricity of Outer and Inner Cores. = Eccentricity due to Big Event.
Uplifted Mantle of Pacific Plate became a Convex Plate, and Depressed Mantle around it became a Marginal Recessed Plate and Back-Arc Basins such as Japan.
In Mechanism where Plates begin to overlap, when Concave Plate and Convex Plate are adjacent to each other, when Plates push each other, Convex Plate smoothly sinks under Concave Plate when Curvature is reversed. If Ccurvature is different, more stress is generated and Energy of Deformation and Fracture is released.
Since Pacific Convex Plate is surrounded by Concave Plates, it is possible to reverse Local Rate and subduct under Marginal Concave Plate in any direction. Therefore, even if Earth tilted due to Collision, Movement Direction could be changed suddenly. Thermal Convection Hypothesis ignores this Fact because it is difficult to explain.

[F]Origin of the Tithys Sea, Movement and stoppage of Antarctica, Evidence for a Plate Tectonics Driving Force.
Wegener's Titian Sea in Pangea is considered to be a Giant Mantle Fragment Impact after Moon Ejection, and a Giant Impact scar from Europe to Indian Ocean.
Himalayan Arc, Java Island Arc, Oceania covered by Australian Continent, and Parts covered by Antarctic Continent are Remnants of Marginal Seas and Deficits of the Present-Day Indian Ocean.
Stopping of Antarctica's Movement is Proof of Plate Tectonics Driving Force because Driving Force does not occur due to Coincidence with Rotation Axis.Origin of Diamonds is Collision of a Planet against Opposite Point of Earth.

Origin Hypothesis of Moon can explain not only Plate Tectonics, but also Origin of Ocean and Deep-Sea Plates in Pacific Ocean, and Mysteries that Whole Plate rotates in one Direction without Wrinkles or Cracks as a Spherical Shell.
Even if we leave Driving Force to Thermal Convection and study Plate Tectonics, we will never be able to explore its Origins.
